Watch "To Where it Begins"

In December 2001, the Derwent Valley Mills in Derbyshire was inscribed on the World Heritage List. This international designation confirms the outstanding importance of the area as the birthplace of the factory system where in the 18th Century water power was successfully harnessed for textile production.

Stretching 15 miles down the river valley from Matlock Bath to Derby, the World Heritage Site contains a fascinating series of historic mill complexes, including some of the world's first 'modern' factories.
